RENSHAPE® SL MATERIALS HELP BRING THE PAST TO LIFE
30 March 2004 - Huntsman Advanced Materials
| Discovered more than 150 years ago during the construction of a railway line near to the site of the Roman Fort of Trimontium in the Scottish Borders, the skull of a
Roman Soldier has been used for a facial reconstruction museum display with the
help of the unique, white, ABS-like RenShape® Solutions SL 7560 stereolithography material. |
The CT scan taken at Borders General Hospital produced a three dimensional data
set of the skull. The data was then sent to Dr Richard Bibb, Head of Medical
Applications at the National Centre for Product Design & Development Research
(PDR) in Cardiff, the UK’s leading supplier of medical models made using
stereolithography technology. Here a detailed SL model of the skull was produced and used as the basis on which
to do the reconstruction of the soldier’s face. The reconstruction was undertaken by
Dr Caroline Wilkinson, a world-renowned expert in this field, based at the Unit of Art in Medicine, University of Manchester, using her extensive sculpting skills to build the facial muscles and skin on the skull to reveal the likeness of the Roman soldier. A second SLA model was then requested to go on display alongside the facial
reconstruction at the Trimontium Museum in Melrose, Scotland. SLA models are
usually transparent, which is ideal for pre-operative planning, but the Museum
wanted a model of the skull that would be easier for visitors to see and recognise as an exact replica of the real skull. To achieve this, Dr Bibb specified RenShape
SL 7560, the only opaque white SL material available. “SL 7560 not only produced a lifelike white skull but also provided excellent accuracy and showed the finest features of the skull perfectly,” said Dr Bibb. “The resin is also tough and durable, so the model can be safely handled, moved and displayed for many years to come.” In addition to the outstanding and unique opaque, white appearance, RenShape
SL 7560 exhibits a good combination of rigidity, durability and temperature
performance. It is easy to process with low viscosity, fast photo speed and high
green-strength.
